Hyperspectral imagery to study submerged aquatic vegetation (SAV) in the Great Lakes region

The hyperspectral images in this collection contain flights over eastern Lake Erie, Lake Michigan near Sleeping Bear Dunes National Lakeshore, and Lake Ontario of the Great Lakes region during the growing season typically June until the end of October. Images were acquired from a manned aircraft with a Resonon hyperspectral imaging camera. Each flight has approximately 200-400 images along the flight trajectory that are in band interleave per pixel (.bip) or band interleave per line (.bil) format. The files are in raw binary, radiance values, and reflectance values. The resolution is typically 1 meter or less depending on the altitude that is flown. Each flight took into account the solar zenith angle to minimize sun glint correction. The data are currently in raw and radiance formats that were converted to radiance using the calibration files provided by the manufacture and no other corrections have been made. The camera is sent annually to be calibrated by the manufacturer. Imagery was collected to study submerged aquatic vegetation (SAV). Funding for this project was received via the Great Lakes Restoration Initiative (GLRI) from the U.S. Environmental Protection Agency (USEPA).
